Re: [qmailtoaster] Fully qualified hostname with multiple domain names
Around three years ago I had some mail rejected because the greeting contained another domain name, maybe the destination had a very strict spam filter, and after changing it to ip the mail was accepted, I remember testing a lot with dnsstuff and following their advices Lucian Eric Shubert wrote: That'd be simple enough to do for dynamic addresses. Still begs the question, why is this considered best practice? There must be a reason of some sort. If it's best practice for servers with multiple domains, why wouldn't it also be best practice for servers with only one domain? I'm guessing it probably has something to do specifically with sending servers. Sending from a dynamic address doesn't work well due to RBLs. The use of smtproutes to relay outbound messages is pretty much required for a server on a dynamic address.

Thanks again! --Adam That's pretty meaningful as bounce messages go. The receiving server doesn't like the host name it's seeing in the smtp session. So the first thing to do is verify what it's seeing. I can't do that since you haven't told me your domain name. If you # telnet my.mailserver.com 25 what do you see after the 220? That should be your fully qualified host name (followed by QMT identification stuff). Change the value in /var/qmail/control/smtpgreeting to contain your fully qualified host name, and I'm guessing that'll fix your problem. I think you'll need to restart qmail after changing this file (qmailctl restart).

Those files are: me, defaultdomain, defaulthost, locals, plusdomain, rcpthosts and smtpgreeting. See the wiki for what should be in these files. I think the solution is to have the me file contain only the server's IP address, and then change the other files above so they just have the word me in them. I don't think putting the word me in any file works. However, I am not sure about rcpthosts (it currently has the two domain names in it - should I leave it alone?) and smtpgreeting (do I just change the first word to me ?). Any advice would be most appreciated. Thanks! --Adam

Re: [qmailtoaster] Setting up horde for mail
The answer is given a few weeks ago. I noted on my wiki (horde is on my todo list): * Installing horde http://wiki.horde.org/CentOS5InstallationNotes on CentOS5? http://192.168.1.70/foswiki/bin/edit/Main/CentOS5?topicparent=Main.MailServerTipsAndTricks. Ignore the stuff about the underlying mailser parts. Tip: run the MySQL? http://192.168.1.70/foswiki/bin/edit/Main/MySQL?topicparent=Main.MailServerTipsAndTricks script manually. Another solution: edit |/$HORDE/imp/config/servers.php| $servers['imap'] = array( 'name' = 'IMAP Server', 'server' = 'localhost', 'folders' = 'INBOX.', 'hordeauth' = false, 'protocol' = 'imap/notls', 'port' = 143, ); and in |$HORDE/config/conf.php| add |$conf['auth']['params']['app'] = 'imp';| and |$conf['auth']['driver'] = 'application';|. I hope it helps. Richard Vinke. Vidyadhar wrote: Hi, Anybody on this list is using horde instead of squirrelmail.

Re: [qmailtoaster] Fully qualified hostname with multiple domain names
Interesting. I don't buy that using an IP address is necessarily the best practice though. Here are my thoughts on this. First, from rfc2821 (http://www.ietf.org/rfc/rfc2821.txt): quote One important reply is the connection greeting. Normally, a receiver will send a 220 Service ready reply when the connection is completed. The sender SHOULD wait for this greeting message before sending any commands. Note: all the greeting-type replies have the official name (the fully-qualified primary domain name) of the server host as the first word following the reply code. Sometimes the host will have no meaningful name. See 4.1.3 for a discussion of alternatives in these situations. For example, 220 ISIF.USC.EDU Service ready or 220 mail.foo.com SuperSMTP v 6.1.2 Service ready or 220 [10.0.0.1] Clueless host service ready /quote quote 4.1.3 Address Literals Sometimes a host is not known to the domain name system and communication (and, in particular, communication to report and repair the error) is blocked. To bypass this barrier a special literal form of the address is allowed as an alternative to a domain name. For IPv4 addresses, this form uses four small decimal integers separated by dots and enclosed by brackets such as [123.255.37.2], which indicates an (IPv4) Internet Address in sequence-of-octets form. For IPv6 and other forms of addressing that might eventually be standardized, the form consists of a standardized tag that identifies the address syntax, a colon, and the address itself, in a format specified as part of the IPv6 standards [17]. /quote So we see that the IP address format is meant to be used when a host is not known to the domain name system. This is clearly not the case in server to server communications, and would thus be inappropriate in a QMT implementation (IMHO). This has nothing to do with virtual domains, nor with the domain names contained in the email messages. Its purpose is strictly to identify the host that's making the connection, in order to aid in troubleshooting. While one might argue that an IP address is a sufficient identifier, it is certainly less helpful for troubleshooting than having a proper fully qualified host name that is properly resolvable via DNS. It's also reasonable (IMHO) for a destination server to reject a connection from a server that provides a name in the greeting message that is not resolvable. If a server were to reject email based on the fact that the domain in the greeting did not match the domain name in a sender's address, that would be ludicrous, given the extent to which relays are used. Based on these observations, my recommendation and practice is to use the fully qualified host name in the /var/qmail/control/smtpgreeting file, as well as the helohost file. This is the same name that's used in a type A DNS record that resolves to the host's address, and is typically also referred to in a domain's MX record. I also believe that this should be considered the best practice. If someone can come up with a reason that this is not the best practice, I'm all ears. -- -Eric 'shubes' Lucian Cristian wrote: Around three years ago I had some mail rejected because the greeting contained another domain name, maybe the destination had a very strict spam filter, and after changing it to ip the mail was accepted, I remember testing a lot with dnsstuff and following their advices Lucian Eric Shubert wrote: That'd be simple enough to do for dynamic addresses.
